Binge drinking affects male and female brains differently, here’s why

Binge drinking affects male and female brains differently, here’s why

While binge drinking affects the health of both males and females, the effect of gene expression in an area of the brain linked to addiction was found to be different, finds a new study. Repeated binge drinking was found to significantly alter molecular pathways in the nucleus accumbens — a region of the brain linked to addiction. But, in females, the genes linked to hormone signalling and immune function are altered, whereas in males genes related to nerve signalling are affected. The study has significant implications for the treatment of alcohol use…

Anorexia nervosa can alter your brain’s response to taste

Anorexia nervosa can alter your brain’s response to taste

Anorexia nervosa — an eating disorder that makes people obsessive about their weight — could alter the brain circuit and impact the taste-reward processing mechanisms, especially for sugar, a study has found.While most people like sweet-tasting things, those with eating disorders associate the taste with weight gain and try to avoid it. The study showed that the brain activation among the anorexia group was inversely connected with any pleasant experience of eating sugar. Those who are already worried about shape and weight become even more concerned. And a strong response that says “feed me” might be…

The Brain’s Need for Glucose: Low Levels Could Predict Alzheimer’s Risk

The Brain’s Need for Glucose: Low Levels Could Predict Alzheimer’s Risk

People often confuse sugar with calories but they are very different. Sugar is a glucose compound which is broken down by the process of metabolism, into simpler molecules with the release of energy. Sugar, a form of glucose is necessary for sustaining life in a living organism. Any living organism or tissue or even a cell eventually dies when the sugar level depreciates. This glucose compound helps in manufacturing energy to perform essential biological processes. Such biological processes taking place inside a living organization leads to the sustaining of respective…

In Losing Weight, Men May Get More Help From Their Brains Than Women Do

In Losing Weight, Men May Get More Help From Their Brains Than Women Do

Image credit: Istock All’s fair in love and war – but not in dieting, apparently. If you’ve ever wondered how it is that men can cut out a few desserts and quickly drop 10 pounds, while women tortuously calorie-count their way to incremental weight loss, a new animal study may have the explanation: It’s in the brain. A class of hormones known as POMC peptides, which regulate body weight, acts differently in female mice than in male mice, according to a collaboration of researchers across four continents. The difference appears…

Depression May Disrupt the Brain’s Emotion Processing Network

Depression May Disrupt the Brain’s Emotion Processing Network

  Regions of the brain that normally work together to process emotion become decoupled in people who experience multiple episodes of depression, a study has found. The findings would help identify which patient would benefit from long term anti-depressant treatment to prevent the recurrence of depressive episodes. “Half of the people who have a first depressive episode will go on to have another within two years,” said study co-author, Scott Langenecker. Disruptions in the network of areas of the brain that are simultaneously active during problem-solving and emotional processing have…
